Fracture and debonding of plastic teeth from the denture base are common clinical problems. In this study, a shear, peeling, load was applied to the tooth-denture base junction. The bond strength of a high-impact, heat-cured denture base to three commercial brands of denture teeth, Bioform, Dentacryl, and TNR, was assessed. Ninety-three percent of the specimens exhibited cohesive failure within the body of the tooth and not adhesive failure at the tooth-denture base junction. Some of the teeth exhibited brittle fracture while others underwent distortion on loading. Dentacryl displayed the highest cohesive bond strenth, followed by Bioform and TNR.
